Holden Astra TS air cond G

[mgvl]

I realise this is not a commodore but anyone got a elect diagram for the air cond on a TS Atsra 1999.

Ive reoplaced the clutch (old one was dead) but now the unit will not work anyway when the air cond button is pressed.

I have not regassed it so does this mean the low / high pressure switches are cutting out the power supply.

Any tips would be useful

regards

ps - the old VL is still running great

the button on the dash sends a signal to the engine ecu, this then activates the compressor clutch it the engine cooling module will allow it.
you really need to have a tech2 connected to the car to diagnose it as the signals are a combination of serial data & regular voltage switching.

Thanks

so no gas (vaccum) probably means the low pressure switch (assuming it has one) is cutting out the compressor clutch ?

yes if it has no gas in the system it wont turn on so you cant destroy the compressor...
